I had a thought about this yesterday... if you don't nominate because you haven't read everything, isn't that, in a way, unfair to the stories you *have* read? If I only read one Elseworlds this year, I can still tell if (IMO) it's a really good story (good grammar, dialog, set-up, etc). And if I think it's Kerth-worthy, why shouldn't I nominate it?
Voting is somewhat different, because that's a comparative thing -- is this story better than that one, or not? -- but nominating isn't. It's just a question of what stories I think are good enough to win awards.
I'll also point out that, by the nature of the process, there's some idiot-proofing. I can nominate a crappy story, or put one in the wrong category (ex. Faux Pas in Best Short Story), if I want to, but I'll probably be the only one doing so. A couple of years ago, there was a short story that I thought was perfect enough to win Best Overall -- so I nominated it there. But I think I was the only one who did

and it didn't make the ballot there. Anyway, point is, the more people we have nominating, the better results we're going to get. So please everybody, send in some nominations! You've only got til midnight (EST) tomorrow!
